So, back again. Have crack the line for the injectors and prime the lines by pumping the b-jeezzus out of it bymut to no success. In the pic there is a line leading into what I have assumed is the injector pump. If that's what you've kindly suggested I crack open, am I right the 1st nut at the end of the elbow opens counterclockwise while holding the one attached to the pump in the position it is now. Last thing I want to do is break something. Thanks for your help. Hope you might be able to illuminate me again.

Then there's these two things behind the pump.....

I am not sure which one is your return and which one is the feed. Follow the line from the filter exit to the pump and crack that one, crank it and see.
 
I am thinking that is your feed, put a wrench on both nuts and loosen the outer fitting, remove it and make sure you have diesel to there. Pump your primer to make sure it is flowing

Which one do I loosen? The one into the pump or the one at the end of the hose? And in either case, which direction? Clockwise or counter clockwise?
 
hose side, put wrenches on both to hold the adaptor in the block. Counter clockwise... righty tighty lefty loosey

When you loosened the injector fittings how loose did you open them? enough to let them breath? Usually a turn or two will do it. When it works it will spay some diesel, lot of pressure there on the injector fitting.
 
Thanks. Will do.

Tried every position with the injectors lines loosened. Nada. I have fuel in the tank fuel to the filter, filter is full, pumped until I couldn't.

So, the air must be between the pump and the filter. Had stared at this fitting wondering if I should touch it but didn't want to break something and risk the Admiral ordering me keelhauled. As it is, I'll be in the dog house until I get the beast running again. Even after I'm sure the reminders of my substandard work will be delivered regularly. Thanks goodness for ear plugs.
 
Where is everybody mounting their VHF handset? In the factory location up on the dash between displays, or elsewhere? Let’s see some pics for ideas!

While I’m enjoying the boat this week, I’ll also be replacing my VHF as part of my on going Garmin helm upgrade. The old Ray230 had no handset (missing), and the wire to the antenna is broken. I’ll be upgrading to a Garmin VHF315 and a new Shakespeare 5225-xt antenna.

The VHF315 also comes with an optional external speaker. Does anyone have any experience with the 315? Is the handset speaker sufficient or will I need the external as well?

I'll be replacing mine too but most boat owners on this forum have suggested ICOM M400BB as the direct replacement for the Northstar NS100 that came with the boat. The Northstar mike cord has literally disintegrated with pieces crumbling off every day. Northstar is no longer in business.

My boat had a Raymarine Ray230 in it rather than the Northstar. I also looked at the Icom M400, but ultimately decided I wanted everything to be from one manufacturer. I like that all my Garmin is easily integrated, and updates directly from one app.

Thats great... What ended up being the magic bullet?

I knew both tanks had lots of fuel. I changed the racor 3 weeks before and the boat ran fine. I changed the secondary filters two weeks later. Stbd started with a few complaints but the port wouldn't. So, I removed the secondary, filled it with clean fuel, reinstalled but primed it at the last few turns (messy) to ensure fuel was reaching it. Couldn't see any sign of fuel at the injector feeds from endless priming so the culprit was air somewhere in between the secondary filter and the injector lines. Followed your advice. Loosened the fitting on the hose end to the pump like you said, pumped the primer for a long time but nothing came out. Had a pal turn the engine over and that's when the fuel started to rush out. Tighted it up right away. The pressure started pushing fuel from the injector line I'd cracked open and just as I tightened it, the beast started.

So happy with myself I took her out for WOT run. Got back the dock, raised the hatch to check all was good and found a lot of coolant in the bilge. I knew I had a slow leak somewhere since I'd added a 1/2 a gallon to the reservoir 10 hours ago and it was almost gone before I headed out. Assuming the added pressure of the WOT run made things really squirt out.

Now, one problem solved and a new one dumped in my lap.

PS. Magnificent ship, love it. Runs like a new boat. 610 hrs now, 85 of which are mine. Previous owners look after and cared for her and it shows. We couldn't be happier. Best summer ever for boating.

Great Job.... good luck on the coolant leak, you are owed an easy one so hopefully it is just loose clamp on a hose!!!!
 
Haven't had the courage to look. SBMAR site suggests the engine can leak coolant at the banjo fitting on the underside of the turbo. Given that the ship is being put on the hard in a week or two for another never ending Toronto sub-zero winter, all the coolant is going to be replaced with the pink stuff. So, sit back, all your questions will.be answered in the Spring :)

Why I never moved to someplace warm is a question that haunts me.
 
We drop down to well below 0° F at times for longe stretches in Jan to Mar. I was told by others that that's the safe thing to do. I'd like to one day do all the winterization work myself but it's all new to me.
 
I had that leak at the banjo fitting under the Port turbo. I put a blue shop rag under there to diagnose the problem as the fitting is not readily visible from the top side. You need to buy a coppyer crush washer to replace what is there. Then just monitor.

Here are a few quick examples:
Coolant/antifreeze - 36F
Pink stuff - 20F
Gasoline -40F
Diesel starts to gel at 32F

your brand name may vary..... but I have never heard of replacing antifreeze with pink stuff.... sounds like a lot of work and expense for the same protection
